Love Her Well: 10 Ways to Find Joy and Connection with Your Teenage Daughter
Two parallel scores from 3 calibrated reviewers and 5 raw-average reviewers.
Z-normalized corrects for reviewer bias (every reviewer re-centered onto their personal scale). Raw average uses simple mean across the broader pool including stddev=0 reviewers. The 21-point gap is the rating-inflation signature for this title — the casual crowd liked it more than discriminating reviewers (a classic inflation pattern).

Summary
Love Her Well: 10 Ways to Find Joy and Connection with Your Teenage Daughter sits at the 6th z-normalized percentile across 5,285ranked books. The z-percentile differs from a raw star average because Rankquant subtracts each reviewer's personal baseline before aggregating — so a reader who rates everything 5 stars carries less weight than one who rates discerningly. Raw-average percentile is 27; the gap between the two measures how much bias-correction changes this title's standing. How percentiles are computed.
